Y = 5x - 2
9y = -2x + 10
9y = 3x + 8
y = (3/9)x + 8/9
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x

Pattern Rule:Add 2
1,2,4,8,16
Pattern:Multiply by 2
Sorry these were simple.
It is 8
As a result of multiply 1.6 times 6, we would also need to apply it to the side as well, and therefore multiply it.
Answer:
Step-by-step explanation:
8/3=3(c+5/3)
multiply both sides by 3
8=9(c+5/3)
divide both sides by 9
8/9=c+5/3
subtract 5/3 from both sides
c=8/9-5/3
change 5/3 to 15/9
c=8/9-15/9
c=-7/9
